STOVE.

Specification of Letters Patent.

Patented Dec. 141, 1915.

Application filed May 20, 1915. Serial No. 29,361.

To all whom t may concern:

Be it known that I, JOHN J. HANNA, a citizen of the United States, residing at Quanah, in the county of Hardeman and State of Texas, have invented certain new and useful Improvements in Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates broadly to improvements in heating apparatus and more particularly to stoves designed primarily for the burning of coal and the like.

The object of the invention is to improve upon stoves of this class to such an extent as to provide a heater which, although being of very simple and inexpensive construction, will be highly efficient in operation and will possess a number of advantageous features.

`With this general object in view, the invention resides in certain novel features of construction and the unique combination of parts hereinafter fully described and claimed.

In describing the invention, I shall refer to the accompanying drawings wherein like reference characters designate corresponding parts throughout the several views and wherein;

Figure 1 is a vertical section of a stove constructed in accordance with my invention; Fig. 2 is asimilar view as seen along the plane indicatedby the line 2-2 of Fig. 1; Figs. 3, 4 and 5 are horizontal sectional views taken respectively on the lines 3-8, 4--4 and 5 5 of Fig. 2.

In these drawings which constitute a part of the application, the numeral 1 indicates an upright cylindrical shell which may be formed of sheet metal or in some cases may be cast. Sheet metal, however, is preferable in view of the fact that its use is much more inexpensive. The upper end of the shell 1 is closed by a top 2 preferably in the form of an ornamental metal casting havj ing a depending flange 3 which fits snugly within the shell 1 and is secured thereto by stove bolts or the like 4, one edge portion of the top tion thereof is equipped with the usual upstanding flange 6 for the attachment of the ordinary stove pipe.

2 being provided with a fuel door'v` 5, while the diametrically opposite edge por-v The lower end of the cylindrical drum 1 is. closed by a solid bottom 7 preferably having an upstanding flange 8 projecting into and bolted to the shell, and a depending annular flange 9 serving as a base to rest upon the floor. Needless to say, the use of the flange 9 is not absolutely essential, since ornamental legs could well be provided in place thereof.

Spaced a suitable distance above the bottom 7, is a horizontally disposed partition 10 shown in the present application as provided with a depending fiange secured by stove bolts to the shell 1. rI`he center of the partition 10 isv provided with a. circular opening 11 beneath which an oscillatory grate 12 is disposed, this grate being preferably, though not necessarily, supported by the brackets 13. Needless to say, the space between the grate 12 and the bottom 7 constitutes an ash pit into which any preferred type of door 14 leads, such door preferably having a damper as 1s common with devices of this class.

Projecting into the central opening 11 in the partition 10 is the lower contracted end of the inverted cone-shaped fire-pot 15, said end being shown in the present embodiment of the invention as provided with an outstanding annular fiange 16 overlying the partition 10 and limiting the insertion of said end into the opening 11. It will be observed by reference to the drawings that although the lower end of the fire-pot 15 is spaced a considerable distance from the shell 1, the upper end of said pot is disposed in Contact with and secured to the intermediate portion of said shell by stove bolts or the like 17, the space between the pot 15 and the shell 1 constituting an air heating jacket.

The upper end of the fire-pot 15 is provided with one or more openings 18 from which hot air outlet channels 19 rise to openings 20 formed in the upper end of the shell 1, while discharging into the lower end of the air heating jacket, is a fresh air inlet 21. Thus it will be seen that when fuel is burning within the pot 15 and cool air is allowed to enter the air heating jacket through the inlet 21, the temperature of this air will be raised considerably, such air being then discharged through the openings 2O into the room and thus affording sources of heat which, when coacting with the heat radiating from the shell, cause the stove to be a highly eflicient heater.

The fresh air inlet 21 is shown in the priate `dan'iper 23, while the amount of .fresh air entering the open llower end of the pipe Ymay be controlled by an additional damper Q4. ln some cases, it inaylbe undesirable -to have the inlet 21 depend from the vantageous features.

stove, on account ofthe :fact that this construction necessitates the forming of an 4opening through the -floor .through -which said inlet may pass, but thisobjection may be readily overcome by `leading fthe inlet `through oneside of the shell l into the `air heating` space, as willbe Vreadily understood -by those skilledin the art to which the invention relates.

Although the use of the same is not absolutely essential Ato the correct Yworking of the stove, l preferably provide yan yoscillatoryhorizontal agitating'bar-Z disposed in contact with'and shiftable laterally over'the upper side of the grate 112,vwherebyclinlers yand the like may 'be dislodged 'from said grate, the bar-'in question being adapted to vbe actuated by lany one of the numerous types of shaker bars now on the Amarket or byfan'y'preferred Vdesign of suoli bar. 'The designs ofthe free end of thefbar 2 5, =however, and that ofthe projection :26 on the grate l2, are preferably-the same, whereby the same shakerbar `may be applied Vto use Yfor actuating both members.

From the foregoing description y taken in connection with the accompanying dravings, it will Abe evident that `although -eoinpla-i'atively simple construction has been pro- `vided for carrying out Ithe object of the invention, the stove will 'be very .efficient in operation and will possess a number of adp Particular emphasis is laid upon the Ifact that the fire-pot l5 gradually extendstow'ard the shell l lfrom its lower to its upper end, since by .this construction, .a thick sheet of'air surrounds the lowerend of the pot and is warmed thereby,

vwhereas when this heated volume I of air rises to the upper yend of the pot, the sheet of presented thereto is comparatively thin, thus allow-ing the ytemperature of such sheet to be again raised before the a'ir is Y The fact that these outlets lead through the 'firepot is also considered a unique feature of plishing probably the best results and for allowingthe entire stove to be disassembled at `will, and inthe preceding description, such details have been described, but it will be evident that Ineed not be limited to such details or to/character of materials and proportion of parts, otherwise :than to fthe extent to which ythe appended claim restricts ine.

A stove comprising an iupright cylindrical shellclosedat its upper and lower ends and :having at opposite points near the uppeivend .of its curved .wall a pair :of air outlet openings, a horizontal partition near the `.lower end of .said shell formed with a central 4circular opening, a tire 'bowl having its .lower end inserted snugly into the opening in vsaid partition, said bowl being .gradually increased in diameter from its flower to its lupper endand having the latter disposed in Contact with the inner side of the aforesaid wall in a Lhorizontal plane immediately belenY `the air outlet openings,

-sa-id :i'iire'bowl having near its upper end a.

pair of air outlet openings disposed immediately beneath the `aforesaid openings 1n ythe wall, fastenerspassing through the contacting-parts of Jthe wall andbowha pair of upright plates secured at their'lower yends to the bowl directly below the air voutlet openings therein, said plates haring their ,upper .ends l ent laterally intocontact .with the aforesaid wall immediately above the air foutlet .openings in .said wall, the upright side edges of said plates being bent laterally Vinto contact with Lthe wall and bow-.lon opposite sides ofthe openings-therein Aand being here again bent -laterally to form `attaching flanges contacting with said wall. and bowl, fasteners passing` through said flanges and ythrough -the -walland bowl, and an upright air supply piperisin through .the closed lower end ofthe shell and opening through-'the partition into lthespace surrounding the bowl.
